It is a 87 IROC, the water pump was recently replaced, and now when I drive above 40 mph and higher, every time I accelerate I hear a pitched sound, then when I let go of the gas it lessens but I still hear it, sounds like a rubbing together pitched sound.

Seeing as the water pump was recently replaced, check the fan belt tension and ensure the belt is sitting properly and routing properly on all its pulleys.
